Ecology of Aipysurus laevis

Main Ref.	Ineich, I. and P. Laboute, 2002
Remarks	Found along seabeds but prefers coral reefs and can rarely be observed in outer reef slopes (Ref. 2353). It is a generalist feeder, swallowing prey found near the seabed (Ref. 2360) and feeds on several species of reef fish in size range, 3 to 15 cm, including small snappers (Lutjanus lutjanus and Lutjanus kasmira), catfish (Plotosus lineatus), red-barred shrimp (possibly Stenopus hispidus). Especially active at night and tends to attack anything bright and moving. It is a relatively curious and unaggressive snake but can be dangerous (Ref. 2352). Females are larger than males and are potentially more dangerous because of higher venom yield (Ref. 2359). Preyed upon by tiger sharks (Galeocerdo cuvier).
